1 Claim. (Cl. 126-85) This invention relates to new and useful improvements in heating stoves, more particularly to a tubular so-called salamander type of heater used in industrial plants `and the like, this type of stove or heater offering a maximum area of heat radiation and having a very high B.t.u. input for a single burner.

It is among the objects of this invention to provide a tubular type of heating stove in which the housing is of uted or corrugated shape and in which a bale is employed as an inner housing or liner to divide the heater casing into a series of independent ilues or ducts for directing the products of combustion over the entire heat radiating area of the stove.

The invention will become more apparent from a consideration 'of the accompanying drawing constituting a part hereof in which like reference characters designate like parts and in which:

Figure l is a vertical cross-sectional view, partially in elevation, of a salamander type heater embodying the principles of this invention;

Figures 2 and 3 are similar views showing a modied form of top or cover for the heaters;

Figure 4 is a cross-sectional view taken along the line 4-4 of Figure l; and,

Figure 5 is a view in perspective of a baille member.

With reference to the several figures Vof the drawing, the numeral 1 designates a housing or heater casing that is uted or corrugated in the manner shown in Figure 4. This casing is mounted on feet 2 which provides a combustion space for a burner 3 connected to a source of gaseous fuel 4 controlled by a valve 5.

Disposed within the casing lis a baie 6, Figure 5, having an inverted conical base 7 which, Ias is shown in Figures l to 3, directs the products of combustion from the burner 3 uniformly into the ilues 8 constituted by the utes of the casing 1 and the outer wall of the bathe 6. As is shown in Figure 4, the burner 3 is shaped to have angularly spaced sections with peripheral portions extending radially into the flues 8.

The top of the heating stoves are provided with covers 9 of inverted dish-shape with a ange 10 nesting in the brackets 11 which support the cover on the tluted casing or housing 1. The covers are provided with vents 9a.' In Figure l, the cover 9 is shown as provided with radiants 12 which deflect the heat absorbed from the products of combustion that have passed upward through the utes 8 and the heat thus absorbed is radiated in a downward direction. In the form of the cover shown in Figure 2, stainless steel wool 13 is employed to absorb the heat and thus prevent the hot products of combustion contacting cold metal which would result in sooting and in the release of deleterious odors.

In the form of cover employed in the structure of Figure 3, a plurality of corrugated steel sheets 14 are employed as rellectors to reect heat in a downward direction.

From the foregoing, it will appear that the iluted heater casing and the cylindrical inner baie provides a series of angularly spaced ilues through which the products of the combustion burners 3 pass upward and are reverberated, as it were, from the cover of the heater. The casing may be from 31/2 to 4 feet long so that the maximum heat from the products of combustion is absorbed by the casing while traveling upwardly. The fluted or corrugated shape of the casing additionally provides a maximum area of heat radiation substantially in excess of that of an ordinary cylindrical housing, as is in conventional use.

By means of the construction herein disclosed and described, a maximum heat is available from a heater of minimum size that takes up a fraction of space in an area to be heated. Also because of the eicient venting of the products of combustion and the equal division thereof by the flutes or ducts of the casing, such a heater may be worked to utmost capacity and yet consume the gases, thereby maximum B.t.u. input can safely be counted upon.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

I claim:

In a heating stove, the combination of ya vertical tubular housing having a longitudinally uted wall, a supporting base mounting said housing, a cylindrical bafe coaxially disposed within said housing with the outer wall of said bale contacting the indents of the fluted housing dividing the space between the housing and baffle into a plurality of uninterrupted vertically extending angularly spaced open ended lines, an integral inverted conical base on said bathe extending below the lower edge of said housing, a burner positioned beneath said conical base, said burner comprising a central portion directly beneath and in contacting relation with the apex of said conical base, and a plurality of radial ported arms, the outer end of each arm extending radially outwardly beyond the outer wall of said baie and into alignment with the lower end of one of said vertically extending hues, with the ports of each arm arranged to deliver ilame upwardly into a corresponding liue, supporting brackets having upturned, outwardly and upwardly extending anges mounted on the upper end of said fluted housing, an nverted dish shaped hood of greater diameter than said housing extending over the top of said housing, the sides of said hood extending downwardly into said upturned anges, vents in the sides of said hood, and means in said hood spaced from the top thereof for deflecting heat from said flues downwardly.
